The problem is that things interact without touching! How do two magnets "feel" each other's presence and attract or repel accordingly? How does the sun attract the earth? We know the answers to these questions are "magnetism" and "gravity," but what are these forces? At a fundamental level, a force isn't just something that happens to particles. It is a thing which is passed between two particles. : http://particleadventure.org /interact.html
Suppose you try shaking someone’s hand. You feel it. Right? As opposed to waving at them from a distance?
But reality depends on the layer you are looking at.
On our scale, if we touch hot things we can burn and we can scrape or skin on rough surfaces.
But if we go way past the cellular level to the atomic level, then there appears to be no such thing as touching at all! In the universe as we experience it, we can directly affect only objects we can touch; thus, the world seems local.
” The effect of one object on another is due to an electromagnetic force producing an action at a distance. As the two objects involved get closer together even down to molecular levels the force gets bigger.”
The entire universe is in a sense ‘untouched’ and ‘untouchable’.
If I try to shake your hand, the atoms in my hand repel the atoms in yours and won’t let them “pass through”. This electromagnetic repulsion is what we experience as touching.
Pushing, Colliding and all related effects are actually electromagnetic repulsive forces at work.
“At a fundamental level, a force isn’t just something that happens to particles. It is a thing which is passed between two particles. Particle physicists have found that we can explain the force of one particle acting on another to INCREDIBLE precision by the exchange of these force carrier particles. One important thing to know about force carriers is that a particular force carrier particle can only be absorbed or produced by a matter particle which is affected by that particular force. For instance, electrons and protons have electric charge, so they can produce and absorb the electromagnetic force carrier, the photon. Neutrinos, on the other hand, have no electric charge, so they cannot absorb or produce photons. The carrier particle of the electromagnetic force is the photon (
). Photons of different energies span the electromagnetic spectrum of x rays, visible light, radio waves, and so forth.
Life is just a neat example of electromagnetic force! ” (http://particleadventure.org).
And thus we are back with Lakshmi Devi. Holding the Universe together.
Atoms usually have the same numbers of protons and electrons. They are electrically neutral, therefore, because the positive protons cancel out the negative electrons. Since they are neutral, what causes them to stick together to form stable molecules? The answer is a bit strange: we've discovered that the charged parts of one atom can interact with the charged parts of another atom. This allows different atoms to bind together, an effect called the residual electromagnetic force. So the electromagnetic force is what allows atoms to bond and form molecules, allowing the world to stay together and create the matter you interact with all of the time. Amazing, isn't it? All the structures of the world exist simply because protons and electrons have opposite charges! : http://particleadventure.org/residual_m.html
